In order to liven up the day at the lake yesterday I took a dive in to the lake. I should have thought to take the transmitter off the lanyard around my neck first. I now have a Spektrum Dx5e that only wants to flash at me. At first the four power lights were flashing even when the switch was turned off so I removed the batteries. Now that it appears to be dried out by putting it in a warm place and also by blowing warm air through it with a hair dryer I have put new batteries in it. It no longer flashes when turned off but does flash when turned on. I cannot get it to function or bind. Any suggestions gratefully received. Thanks, Ian.

OK
Don’t put power any more.
Wash it inside and out - serious soak with distilled water. You will have dissolved salts even in pond water that can short the electronics - might have already happened.
Dry it slowly not fast - put it next to your hot water tank or similar, and leave for at least a week.
Be patient and don’t power it up under any circumstances until it is really dry.

Agree with Snowwolflair :}
As well as distilled water, people have soaked in meths - which dissolves out the water and evaporates more easily
and as he says a slow dry should bring it back to life.
Was there anyone to score your dive for Technical content and Presentation?

Whisky works as well, the same principle. I once drowned a very expensive JR PCM 10 receiver with helicopter in a trout lake, all I had was a very expensive single malt so all the avionics pack got washed in that and dried in the airing cupboard only the onboard battery checker failed to work afterwards. And after thinking what fishes do in the water, I didn't drink it afterwards !!

I'd rather have drunk the whisky.....

With the whiskey, its a terrible waste, but also a bit fraught with peril - any alcoholic drink with colour and flavour will leave deposits on whatever surfaces it comes into contact with. If they then come into contact with a damp atmosphere there is the danger that they come back to life as an electrolyte, and allow corrosion and/or circuit misoperation.
Lets just hope that kiwis' electronics, when they got dunked, didn't have the "forget everything" program started.

I had a further 3 years, all year round use from all the equipment cleaned in this way and then sold it, the new owner had a further nine months of use out of it all before he ran out of fuel and hadn't learnt to auto. Pity really as it was a Vario jet Ranger with a OS 120, 4 stroke engine in the livery of the Treasure Hunt Helicopter, all airbrushed by a local artist. Perhaps its the quality of the whisky that counts !
